Ref-GS: Directional Factorization for 2D Gaussian Splatting

Mesh Rendering Mesh Rendering Mesh Figure 1. Our Ref-GS method generates photo-realistic renderings with view-dependent effects while also enabling accurate geometry recovery. The top row shows a comparison of renderings for a scene with specular reflections, along with the recovered normals and mesh. The bottom row demonstrates our successful reconstruction of the geometries of the 'reflective table center' in the 'Garden' scene [2] and the 'windshield' in the 'Truck' scene [13] , which existing methods typically fail to handle.
